rs4072037

This case-control study of 1,115 gastric cancer cases and 1,172 Eastern Chinese controls identified six SNPs (rs13361707, rs2294008, rs4072037, rs3762272, rs2274223, rs80142782) associated with increased gastric cancer risk with ORs ranging from 1.19–1.47. A predictive model combining these genetic variants with BMI achieved an AUC of 0.684 compared to 0.653 for BMI alone, and revealed a gene-environment interaction between low BMI and genetic risk variants.

Turkish case-control study examining TRAIL and TRAIL-DR4 gene polymorphisms in gastric cancer. Compared TRAIL C1595T (rs1131580) and TRAIL-DR4 C626G (rs20575) genotype frequencies between 50 gastric cancer patients and 163 healthy controls. No significant association found between either polymorphism and gastric cancer risk (p>0.256, p>0.189) or clinical parameters including tumor stage, lymph node involvement, distant metastasis, and perineural invasion. Serum TRAIL levels were also not significantly different between groups (p>0.33).

A case-control study of 692 stomach cancer cases and 774 controls in a Han Chinese population examined associations of four GWAS-identified SNPs with gastric cancer susceptibility. PSCA rs2294008 (CT: OR=1.37, 95% CI=1.07-1.74), PSCA rs2976392 (AG: OR=1.30, 95% CI=1.02-1.65), and PLCE1 rs2274223 (AG: OR=1.48, 95% CI=1.15-1.90) were all significantly associated with increased stomach cancer risk, while MUC1 rs4072037 (CT: OR=0.77, 95% CI=0.60-0.98) was protective. Carriers of multiple risk genotypes had significantly elevated cancer risk.

Letter to the editor discussing peritoneal carcinomatosis from gastric cancer management and genetic susceptibility. Authors discuss GWAS findings including PSCA variants rs2976392 and rs2294008 at 8q24 associated with diffuse-type gastric cancer in Asian populations, and SNPs at 1q22 (rs4072037) and 10q23 (rs2274223) associated with gastric cancer risk in Chinese populations. The letter emphasizes the need for prospective randomized trials and future GWAS studies to identify novel genetic loci for peritoneal metastasis susceptibility.

Case-control study of 692 stomach cancer cases and 774 controls in a Chinese population found significant associations between four GWAS-identified SNPs and gastric cancer susceptibility: PSCA rs2294008 (OR=1.37, 95% CI=1.07-1.74), PSCA rs2976392 (OR=1.30, 95% CI=1.02-1.65), and PLCE1 rs2274223 (OR=1.48, 95% CI=1.15-1.90) increased risk, while MUC1 rs4072037 (OR=0.77, 95% CI=0.60-0.98) was protective. Subjects carrying 2-4 risk genotypes had significantly increased stomach cancer risk (OR=1.30, 95% CI=1.03-1.64).

This candidate gene association study examined 218 postmenopausal women at high breast cancer risk, testing 79 SNPs in steroid metabolism, receptor, cell cycle control, DNA repair, and carcinogen metabolism genes for associations with abnormal breast tissue cytomorphology (RPFNA atypia) as a biomarker for HRT-related breast cancer risk. Key findings: RAD54 Gln929Glu (rs3088074, OR=1.74), TFR Gly142Ser (rs3817672, OR=1.98, p=0.0025), VEGF 3'UTR (rs3025039, OR=2.12), and ACE I/D (rs4646994, OR=0.55) were associated with RPFNA atypia. RAD23B Ala249Val (rs1805329) showed strongest association with worsening cytomorphology on HRT versus off HRT (p=0.0009) and ERCC1 3'UTR (rs3212986) was borderline significant (p=0.0015). Results suggest DNA repair gene polymorphisms may modify breast tissue response to exogenous estrogens.

Case-control study of 692 stomach cancer cases and 774 controls in Han Chinese examining associations between four GWAS-identified SNPs and gastric cancer risk. PSCA rs2294008 (OR=1.37), rs2976392 (OR=1.30), and PLCE1 rs2274223 (OR=1.48) showed increased risk, while MUC1 rs4072037 was protective (OR=0.77). Combined risk genotypes increased cancer susceptibility.

Case-control study (692 cases, 774 controls) in Han Chinese population examining associations of four GWAS-identified SNPs with stomach cancer risk. PSCA rs2294008 (CT vs CC: OR=1.37, 95% CI=1.07-1.74), PSCA rs2976392 (AG vs GG: OR=1.30, 95% CI=1.02-1.65), and PLCE1 rs2274223 (AG vs AA: OR=1.48, 95% CI=1.15-1.90) were associated with increased stomach cancer risk, while MUC1 rs4072037 (CT vs TT: OR=0.77, 95% CI=0.60-0.98) was protective.
